Think about it!

The astonishing scenes of Master Tang's invention and creation replayed in Linfield's mind, making her feel more and more that Tang Ning was not joking with her, "other", this is a concept proposed by someone in the popular science fiction world recently, which means intelligent life forms other than human beings themselves.

Vice Chairman Lin, who originally thought that he and Tang Ning were the co-founders of the Earth Empire, suddenly felt that the distance between himself and Tang Ning was 100,000 miles, and he was no longer the person who was close at hand.

After thinking carefully and deeply for a long time, Lin Fei said quietly: "It's really a very bad story, is it just a story?" ”

Downing: "You have to think it's just a story, it's a story, you see, I didn't try to convince you. I'll move on. Tell me what our first generation of rejuvenating human beings was like. First of all, of course, we can go back to childhood for a certain period of time, up to 12 years old, but it depends on the individual, some people only go back to 15 years old.

And we can't actively control the time to return to childhood. Human cells are mitotic, this filament, refers to the filamentous matter tied between the telomeres at the time of division, and the natural lifespan of human beings is about 120 years, which is determined by telomeres.

With each time a human cell undergoes mitosis, telomeres become shorter and eventually lose the ability to divide. The essence of rejuvenation is to make people's cell telomeres return to the length of their childhood. It sounds like a wonderful thing, but it also has imperfections.

We consume life twice as fast as normal people, that is to say, our theoretical natural life expectancy is only 60 years, and I am 50 years old this year, that is, I have to return to the time period of childhood, from now on, I will be more dangerous every year I pass, and theoretically I will never be more than 60 years old.

Over the years, I've been so obsessed with the beautiful beginnings in front of me that I've almost forgotten what my parents have told me since I was a child. A few days ago, I suddenly fell into a coma, and such a huge physiological change made me recall in horror that I was a rejuvenated physique.

I was a huge science history buff in the place where I lived, but the huge bioengineering secret about rejuvenants was not fully included in the public information, so I didn't even know the details, and my parents only knew a rough idea.

According to my estimates, it will take about 50 years to study the emergence of human technology from lighthouse jellyfish to rejuveniles, which is almost a time that I cannot cross, so ...... Now there is no such technology on the earth, and if I can't return to my childhood under the careful care of my old society, I will consume my life in 10 years, and my survival situation is very bad, and I am a little scared now. ”

After a thousand words, I didn't know where to start, and finally Linfil remembered the key: "So, why did you come to Earth?" You're the only one? ”

Tang Ning: "Our place is very technologically advanced, and it has entered an imaginary society. I'm going to explain the term. Imaginary numbers were invented by the 17th-century numerist Descartes to represent numbers with negative squared values.

Unexpectedly, it was later discovered that imaginary numbers can correspond to the vertical axis in the plane, and form a plane together with the horizontal axis of the real number. If we keep our eyes fixed on real numbers, all human beings can enjoy is a line, which is equivalent to a one-dimensional life.

And if we can fully accept the imaginary life, then human beings will magnify the welfare of the individual by an infinite multiple. This imaginary life is actually the life of virtual reality. Video games are only the most primitive stage of imaginary life. In our place, the senses of human interaction with reality, sight, hearing, touch, smell, and taste, can all be blurred.

The virtual process is extremely high, and it is almost impossible for humans to tell in the virtual world that this is a world created by human scientists, engineers, and artists together.

The resources on the earth are limited, and the resources available to ordinary people are even more limited. The so-called great material abundance soon reached its limits on Earth. I live in a society where a per capita income of 1,000 euros can afford to consume huge amounts of resources, putting a heavy pressure on the planet's resources.

When the per capita income reaches about 300 euros, the population of the whole planet begins to grow negatively, for this reason, the planetary government approved the nursery project, so that human reproduction into the 'oviparous' era, the baby in the nursery only takes the sperm and eggs of the father and mother, but it is completely developed in the nursery, like an egg, no longer needs the mother's natural pregnancy and delivery.

The fact that it was so easy to 'have children' and that people of all countries were born in a race pushed the population to the horizon - a planet the size of the Earth is dotted with 40 billion people. Antarctica, the Arctic, the oceans, and space are all inhabited.

In view of the fact that real number resources are in short supply, and most people are unwilling to leave the planet, the planetary government has made great efforts to promote the concept of imaginary life, so that the time for human beings to live in the virtual world has increased significantly, at the beginning it was only two or three hours, and finally, the average time of each planetary citizen staying in the virtual world is 20 hours. There are quite a few dead houses who often stay in the virtual world for months and do not come out.

The world of imaginary numbers is the real resource, which is extremely rich, so rich that you can't imagine. Therefore, at that time, human beings were more and more fond of imaginary number life, and some scientists did research, and it was estimated that people living in the real number world for more than an hour would produce mild depression.

Some people who work in the world of real numbers have to rely on anesthetic drugs to work normally for 3 hours, which is already the limit. ”

The sensory organs of the real science recipients are different from others, and when she heard this, Lin Fei'er actually thought: "How beautiful is the imaginary life?" ”

Tang Ning didn't forget her original question, and continued: "Therefore, reducing the punishment for human beings to enter the world of imaginary numbers is already very powerful, like going to prison.

And coming to this earth is the most severe punishment, and we call this punishment exile there. I was sent to your earth at the age of 25 for violating the planet's laws regarding machine people, one of the highest punishments.

You've guessed right, I'm the only one who came to your earth. ”

Originally, the reality that Downing was nearing the end of his life was difficult for Linfield to accept, perhaps even more difficult to accept than the critical illness of old Mr. Faraday, but the ensuing hard science impact diluted her sadness, and a strange feeling rippled in her heart.

Linfield: "...... You're a criminal......"

Downing: "Yes. However, it is not an ordinary criminal, it is an extremely dangerous criminal, because the limitations of human intelligence that I have cracked on the human body may lead to another rebellion. There are very few planets developed in my solar system, because humans have limited their intelligence, and humans themselves are willing to colonize to outer space on a large scale.

At the time, I thought it would be stupid to impose restrictions on the machine, so I joined a hacker group that thought the same way as me, and learned a lot of incredible ways to crack it. Some of them are better than me, and I think that after all, human beings will not be able to resist the betrayal of internal humans, and one day, human beings will be eliminated by artificial intelligence.

Thankfully, I got out of there, and maybe I'll be even sadder when I see that happening with my own eyes. The idea of a young man is very different from what I think now, and my current mentality is the same as that of the legislature of the planetary government, desperately trying to prevent humanity from being replaced. For yourself, for your family, for your friends and family. I don't want to see them have an accident, young people are really heartless. ”

Linfield: "Your Earth resembles ours?" Does the path you have traveled foreshadow that our planet will also go in that direction? ”

Downing: "Yes, it's very similar, it's just the same earth, different dimensions. So much so that some of us scientists call this kind of exile an exile with a time machine, and ordinary people can't understand the terms of different dimensions, so they call your earth the earth 200 years ago. And I am equivalent to coming from the earth in 200 years. ”

Linfield: "Well, explain to me what dimensions are, in your place. The dimensions I understand are the vertical and horizontal axes you just mentioned, and at most one z-axis to form the whole space. ”

Downing: "Okay...... That's a good question. I'll have to start from a long way away. With the development of observation technology, we have now observed the wave nature of electrons, which move around the nucleus in its orbit in the real yàn chamber in Tianjin.

This orbit is not a very clear line, the electron will appear here and there, and its appearance is a matter of probability, some positions have a high probability of appearing, and some have a low probability. ”

Downing took out his mobile phone and drew the probability cloud of electrons in the drawing app to show Linfell.

Downing: "It's a very intuitive graph, and it can actually be represented by a formula, which we call the Schrödinger wave equation there. ”

Downing wrote the Schrödinger wave equation, and its complexity made Linfield a genius as good at mathematics a little unbearable, but as soon as he connected with the electron cloud he had just drawn, he initially grasped the mathematical simplicity and beauty of the wave equation.

Seeing that Linfield finally nodded slowly, as if he understood the wave equation, Tang Ning continued: "The electron cloud can be interpreted in many ways, but once scientists list this wave equation, it is clear that electrons, like photons, are both particles and waves.

Photons are pure energy, and fluctuations do not trigger scientists' sensitive nerves, but ...... It's strange that electrons, with mass, fluctuate. This is a contemplative and terrifying phenomenon, as it leads to the following inferences.

We can first feel the relationship between position and momentum from the macroscopic object. There is a proverb that says: you can't step into two rivers at the same time. Later, it was said that it is impossible for people to step into the same river at the same time. What does that mean? Because man is in motion, when is he in the river when he is crossing the river at a very high speed?

The faster we cross the river, the harder it is for us to determine when he set foot in the river, that is, to see where he is. Conversely, the slower we cross the river, the more we can see his position, but at this point he was forced to slow down.

For the observer, there is a contradiction between determining the position of the person crossing the river and the speed of the person crossing the river. Since the person who crosses the river wants to cross the river, he must have a certain speed, which is similar to the movement of electrons, which not only have speed, but also very fast, the closer they get to the nucleus, the faster they must be, otherwise they will be sucked in by gravity.

What's worse is that the motion of the electron is still fluctuating, and the speed is different from moment to moment, so it is even more difficult to determine its speed and further calculate the momentum. When an electron is at a certain point, it is difficult for us to know its speed because it is variable speed.

When we want to examine the velocity of electrons, there must be a distance to calculate more accurately, because the motion of electrons is not uniform, at least you have to see that it goes through a period of fluctuations. At this time, another science summed up this pair of contradictory physical quantities and called it the 'uncertainty principle'.

The uncertainty principle can be found in all parameters at the particle level, energy and time, because energy is related to velocity and time is related to distance. It is found in angular momentum and angle because angular momentum is related to velocity and angle is related to position.

Once the uncertainty principle is universally accepted, there will be even more terrible derivations. ”
